Getting Started

Follow these steps to integrate SuperDeck into your Flutter project:

1. Install the superdeck package by running the following command:

   flutter pub add superdeck

2. Import the superdeck package in your Dart code:

   import 'package:superdeck/superdeck.dart';

3. Initialize SuperDeck and run the app.

   void main() {
     runApp(const SuperDeckApp());
   }

4. Create a slides.md file at the root of your project.

5. Configure your pubspec.yaml file to include the necessary assets:

   flutter:
     assets:
       - assets/
       - assets/images/

The assets directory is used to slide and asset references, while the assets/images directory is specifically used for storing images used in your presentations.

::right::

# Product B
- Feature X
- Feature Y

Sections

If the first tag that is found is ::right:: everything before this tag will be placed on the ::left:: section.

You can control the content options for each section on the front matter of the slide.
